Working Theory

A popular modification amongst bike owners is to install an aftermarket high flow pipe, a header, or a full exhaust system to unlock the power of the motorcycle. Nowadays, exhaust gas is controlled through one to up to four exhaust o2 sensors on motorcycles. exhaust o2 sensors control the fuel management system and monitor the converter function on up-to-date emission controlled bikes fitted with catalytic converter. When the aftermarket exhaust is installed on your Indian Chief Bomber EFI, the result is an exhaust oxygen sensor related check engine light MIL code alerting the PCM that the exhaust gas consistency is changed. The modified engine now produces a larger amount of exhaust gases than allowed. Obviously you do not want to ride your motorcycle with a constant MIL light, besides your Indian Chief Bomber EFI will not pass emissions inspection in many US states or countries with an illuminated MIL light. The ultimate solution is to install an O2 sensor simulator wired up to the downstream oxygen sensor’s harness in order to simulate a properly functioning lambda probe. EZ CEL Fix motorcycle oxygen sensor eliminator delivers the Power Control Module with mimicked, fluctuating voltage signal and tricks the Power Control Module into thinking the emission is normal. Your Indian Chief Bomber EFI oxygen sensor simulator will allow you to ride your motorcycle with aftermarket exhaust and still keep the CEL off.

When check the engine light is triggered, the engine runs in ECU safe / limp mode, which results in sluggish acceleration and spoiled fuel mileage. EZ CEL Fix Indian Chief Bomber EFI O2 Sensor Simulator eliminates the o2 sensor, thus you can remedy the annoying ECU codes. Magnum EZ CEL Fix bike Oxygen sensor simulator is available to all motorcycles fitted with 1 up to 4-wire narrowband zirconia exhaust gas oxygen sensors functioning in the standard 0 up to 1.0 Volt fluctuating voltage range. EZ CEL Fix Indian Chief Bomber EFI Oxygen sensor simulator remedies all oxygen sensor related ECU codes caused by modifications made to your Indian Chief Bomber EFI’s exhaust. This Indian Chief Bomber EFI O2 Sensor Simulator is adjustable, making you enable to adjust the Air Fuel Ratio within certain range yet complies with the requirement of Electronic Control Unit.

Notes

Headers require both up- and downstream Oxygen sensor emulation on those bikes fitted with both up- and downstream oxygen sensors.

Oxygen sensor simulator is a racing part. It is not CARB approved. Please be aware of the bylaws and regulations, O2 sensor eliminator is not street legal in several US states and countries.

Indian Chief Bomber EFI EZ CEL Fix bike Oxygen Sensor Simulator is a must-have part if you are about modify the exhaust. Are you chasing after the ultimate solution for CEL issue? Then you’ve come to the right place.

Are you concerned with remedying the ECM safe / limp mode was tripped by your exhaust modification? Are you sick and tired of resetting the Electronic Engine Management repetitively? Get rush and install our oxygen sensor emulator on your Indian Chief Bomber EFI. With minimum efforts you can resolve the ECU Safe mode all on your own, as long as you are mechanical and electrical minded. Conduct the setup and enjoy the service engine soon light-free riding.

How can I figure out my sensor is a zirconia type?

Zirconia type oxygen sensors have 1 to 4 wires. 1 to 3 wires indicate a zirconia narrowband O2 sensor definitely. In the case of 4 wires, two of the wires have to be identical for heater, whilst the rest two wires have to be different for signal sender and signal ground. Always reference the sensor-side colors of the wires coming out off of sensor head. ECU-side colors may convert through the plugs.

How to find out if it's a narrowband or wideband?

Typically 1 to 4-wire sensors are narrowband. There are exceptions though. A narrowband oxygen sensor's signal is constantly fluctuating in a range of 0 to 1.0 Volts depending on oxygen content in the exhaust gas. Any oxygen sensor that produces higher voltages, is determined to be a wideband oxygen sensor. Keep in mind, although a 4-wire O2 sensor can be wideband too, in common sense only 5 or 6-wire sensors are called wideband. If your sensor has more than 4-wires, oxygen sensor is not applicable.

Which sensor has to be tricked?

In general: the downstream but upstream has to work flawless in full range. If you intend to buy a simulator hence decatting, header or modified exhaust, the downstream sensor has to be fooled by all means. See position diagram .

Headers or precat gutting requires upstream simulator as well.

Questions and answers

- Can I be positive this chip fixes my CEL issue for good and all? - Yes, Magnum oxygen sensor simulator produces a random fluctuation having assigned with suitable cycle and wave accepted by the ECU. Rest assured, all oxygen sensor signal related codes will be gone. Upstream sensor if any has to be in good condition though. Please see prerequisites pertaining to sensor type and quantity of simulators. - What if I simply eliminate factory oxygen sensor? - Oxygen sensor removal will not remedy CEL issue. Suitable fluctuating signal is fundamental to be delivered by the ECU. Zero volt signal triggers another trouble code. - Why is it so important to cancel the trouble code? - While check engine light is on, ECU restricts the engine performance and Motorcycle is running in safe / limp mode. MPG is also affected negatively. - Do I need to buy a heated simulator or I can stick with this cheaper EZ CEL Fix? - If you can use the heater of the factory oxygen sensor(s), you may wire up this #795 EZ CEL Fix. Heated simulator #661 allows you to remove or eliminate the stock oxygen sensor completely. - What about 'oxygen sensor bungs' 'mini cats' or any other piggybacks are also supposed to sort our FI problems? - The market is teeming with physical gadgets aiming to fix CEL issues. Vast majority of them doesn't take effect on OBDII Motorcycles made after 1996. They often don't work even on early fuel injected cars. If your, motorcycles had been manufactured after 1996 or you ride an early model controlled by a sensitive ECU, these gadgets won't help. The definite solution is a circuit conditions realistic signal, as if a working oxygen sensor would be screwed in the factory exhaust. - Can I rally my two harnesses into one simulator? - No, simulators can't be spliced. Get rid of oxygen sensor related CEL issue yet today. Injected gasoline engines controlled by Electronic Control Unit (ECU) or alias Electronic Control Management (ECM) have oxygen sensor or O2 sensors to measure the amount of oxygen contained in the exhaust gas. These sensors deliver the ECU fluctuating voltage according to the actual oxygen consistence of air fuel mixture. When exhaust system is decatted or heavily modified, ECU is reading an oxygen sensor signal being inconsistent with other engine sensor's signal, or signal is out of the range yet accepted, an O2 sensor-related trouble code will be triggered ending up in check engine light issue. CEL or MIL or FI errors abbreviate these failures. While check engine light is on, ECU runs in so called lean limp mode. Safe mode restricts both the fuel trim and the ignition timing and develops an overall limitation on performance, until problem diagnosed and resolved definitely. Therefore if you modified your engine with any upgrade causes the oxygen sensor deliver lower signal than normally, you need to wire up an Oxygen Sensor Simulator. Although your ECU will be tweaked, mixture's air fuel ratio still will remain incorrect hence decatting or any other exhaust modification. Simulators help you remedy CEL problems but will not achieve that basic remapping is crucial when decatting or modifying an exhaust. You might be interested in our further performance chips in order to boost engine horsepower, improve fuel efficiency or both at the same time.

Wiring

Cut the harness of the oxygen sensor.

See colors operations of each wire in car wiring diagram or search for your combination in the table below.

Connect the proper wires with terminals or solder them in place. (Hydrochloric acid recommended if soldering.)

Contact the red cable of the red/black dual wire to the ignition feed + 12V, and the black to the engine frame or battery negative.

Mount the unit to any fixture as far from heat as possible. Lowest temp recommended.

Notes

Simulator is waterproof but not submersible.

Always insulate contacts!

Make sure, check engine light refers to a valid oxygen sensor related trouble code, other errors cannot be remedied with a simulator.

If necessary, reset the ECU before readjustment because ECU does not "forget" errors necessarily and check engine light might keep on illuminating after installation of the simulator.

The difference between front and post sensor’s voltage is also monitored. If deviation is excessive, an error code might be triggered on the downstream pier, even though the issue is not caused by the downstream sensor. Upstream sensor also can be slow or stuck, so downstream sensor has to be in mint condition.

Usually aftermarket header ruins the upstream oxygen sensor signal. If so, upstream sensor has to be eliminated as well.

Although EZ CEL Fix makes you enable to adjust the air fuel ratio within a certain range, basically it is not intended to remap the fuel trim. If you are about to override the factory lean fuel programming or you want to optimize the potential of your exhaust upgrade, feel free to check out our fuel controllers .

EZ CEL Fix Oxygen sensor eliminator has to be powered on ignition feed DC 12V. Never connect hot wire to constant battery voltage. This wiring may lead to battery drainage also may fry the circuit.

Emission test result depends on the criteria of your local emissions inspection. Simulator is neither supposed to improve emissions spoiled by an aftermarket pipe or any other upgrade, nor restore factory emissions required for a smog inspection. It is solely intended to help you get rid of ECU safe mode triggered by check engine light issue. It will not allow you to preserve factory emissions level. Simulator tricks the computer delivering mimicked signal is accepted by the ECU but it can’t purify the fume electronically.

The simulator is waterproof but not submersible.

EZ CEL Fix’s signal is set to factory 0.9…0.95V top voltage. Don't adjust signal related screw#1 until CEL issue is resolved. Basically screw#1 should not be dialed unless you want to modify air fuel ratio. We don't bear responsibility for CEL shut down, if signal is not set to the top voltage above.

hell of difference in take off

item shipped awesomely fast after installed this o2 by pass on my scooter one hell of difference in take off and throttle response, scooter runs smoother with no CEL on, thats what shes been craving for

count on exceptional technical support

would have been nice to read all the do’s and don'ts on the web site before you go ahead with your order, to check which wires to cut and where to tap into with chip’s wires, manual you receive in this respect leaves a bit to the imagination, telling the truth, you can count on exceptional technical support though that is sufficient to make this fuel chip work as advertized

my bike was unmodified expect for (removed) pipes, bought this simulator to Lightning to get rid of engine FI light but product wasnt customized to my dual o2 sensor bike, so needed to buy another, although got 10% off i wasnt tickled to be waiting

o2 bypass chip works exactly as expected

Case and point this is an eminent transaction,part description is accurate and the o2 bypass chip works exactly as expected.Eliminator made me enable to run with my new (removed) pipe without MIL. Thanks MAGNUM.
